I am honored to be a part of RootsTech 2025 with a presentation on Y-DNA testing strategies. Whether or not you are attending RootsTech, you can watch my prerecorded session online at no charge by logging into FamilySearch. There are also a great number of other online and recorded sessions to watch. RootsTech Y-DNA Presentation … Read more
In the last post, I presented a strategy for expanding a genetic network of shared matches all within a DNA testing website. The strategy is called Viewed Match Switching. Now, I present a similar but more holistic strategy using Gephi network graphs. This process is more demanding of our mental and computational resources, but it … Read more
If you’re using genetic networks to analyze your DNA matches, then you need to also use viewed match switching. This DNA analysis strategy helps you find more relevant matches for the ancestor being researched and construct a more robust proof argument. I first introduced viewed match switching in my genetic network blog series in its … Read more
After the success of my Big Y-700 Video Learning Module Series, Genealogical Publishing Company honored me with an opportunity to review Roberta Estes’ new book titled, The Complete Guide to FamilyTreeDNA: Y-DNA, Mitochondrial, Autosomal and X-DNA. As a fellow genetic genealogist, I was eager to review Roberta Estes’ book. While I’m an “Ancestry first” person … Read more
You’ve done the hard work in identifying a genetic network and analyzing the matches (Part 5). Now comes the fun part — conducting documentary research. Not that the other steps were not enjoyable and were void of documentary research, but now we get to apply our prior DNA observations within new record groups and attempt … Read more
In genetic genealogy, the more matches we have, the greater our ability to make ancestral discoveries. Having more data points increases our confidence with the sub-clusters observed within genetic networks as discussed in the previous post in this series (Part 5). It can also help us prioritize our research efforts as we progress into documentary … Read more
In the previous blog posts, I defined genetic networks (Part 1), discussed the inclusion and exclusion criteria for matches within the network (Part 2), described how to find them (Part 3), and demonstrated how to efficiently review your matches’ family trees (Part 4). Now, I describe how to use Ancestry Pro Tools’ Enhanced Shared Matches … Read more
In the previous blog posts, I defined genetic networks (Part 1), discussed the inclusion and exclusion criteria for matches within the network (Part 2), and described how to find them (Part 3). Now, I demonstrate how to efficiently review the family trees for the shared matches within a genetic network to discover your unknown ancestors. … Read more
In the first two blog posts, I defined genetic networks (Part 1) and discussed the inclusion and exclusion criteria for matches within the network (Part 2). Now, I describe how to easily find genetic networks within your list of autosomal DNA matches. As in prior posts, I label these matches as A (test taker), B … Read more
In Part 1 of the Genetic Network blog post series, I defined genetic networks and provided several visualizations for the types of DNA matches forming genetic networks. I labeled these matches as A (test taker), B (match being viewed), and C (matches that match both A and B). As the Part 2 title suggests, there … Read more
